PAPER-FILE.

SPECIFICATION forming part of Letters Patent No. 447,067, dated February 24, 1891. I

Application filed December 16,1890. Serial No. 374,877. (No model.)

To all whom it may concern.-

Be it known that I, ALBERT B. DICK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Paper-Files, of which the following is a specification.

The object of this invention is a paper-file the arches of which shall be opened for the filing of papers or closed to prevent loss of papers by a positive movement in each direction, and ,the mechanism of which, affecting said movements, shall not be liable to be operated accident-ally.

The invention consists in providing the movable sections of a double-arched paperfile with a connecting rod or bar provided with a cam-cut groove and operating this bar or rod, and consequently the movable sections of the arches, through a swinging lever preferably carrying a friction-roller entering the cam-groove of said rod or bar.

In the accompanying drawings, forming a part of this specification, Figure 1 is a plan view of a paper-file embodying my invention, showing in dotted lines the base-board with which it is usually employed. Fig. 2 is a front elevation showing the swinging lever thrown to one side of its vertical position,the movable sections of the arch file being lowered and the file ready to receive papers, &c. Fig. 3 is a rear elevation showing the lever. in its vertical position, the movable sections then being in the raised position closing the arches of the file. Fig. 4 is a side elevation of one of the arches, looking in the direction of the arrow, Fig. 3, with certain parts in section on the plane of the line 4 4, Fig. 3.

A is the base of the paper-file usually attached by screws B B to a suitable bed or support. The base A serves to support the arches O O and the movable section D D, the latter serving to complete the arches 0 down to the- I base A when in the raised position. The arches C are adj ustably supported in nipples E E cast or otherwise formed on the base A,

arches in any desired position. The sections D D are hollow and fit loosely over posts G ing the sections D D is a cross-bar H, which cross-bar has a depending flange or projection I, in which is cut a cam-groove J. Engaging with this groove is a friction-roller K, carried on a pintle L, projecting from one end of a lever M, which lever swings on a pin N,

In operation all that is necessary to prepare the file so that papers may be filed on the arches C is to swing the lever M to one side, when by the action of the roller K and the cam-grooves J the sections D will be lowered. To close the sections so as to complete its vertical position.

What I claim is 1. In a double-arch paper-file, thecombination, with movable sections completing the arches of the file, of a cross-bar connecting said sections, a swinging lever, and a cam-connection between said lever and cross-bar, substantially as set'forth.

2. In a double-arch paper-file, the combination, with movable sections completing the arch es of the fi1e,of a cross-bar connecting said movablesections, a cam-groove J in said crossbar, a swinging lever M, and a friction-roller K, carried by said swinging lever entering said cam-groove J, substantially as set forth.
